4.8 prints
t.ii: In function ‘void _Z3fooi.constprop.0()’:
t.ii:14:8: warning: array subscript is above array bounds [-Warray-bounds]
z[i] = i;

which isn't perfect either. Is there a way for the C++ FE to get at the
original function decl that was cloned? Like with

does former_clone_of apply recursively? Thus can we have a clone of a clone?
Is there a way to "pretty-print" the kind of clone? That is, say
<clone with foo = 1> for a ipa-cp clone with parameter foo replaced by 1?
